Splenogonadal fusion (SGF) is a rare congenital malformation that occurs during embryonic development. SGF typically presents as a left-sided scrotal swelling, left inguinal hernia, scrotal mass, or cryptorchidism. Therefore, it is easily misdiagnosed, and unnecessary orchiectomy may occur. This study aimed to report a rare case of SGF.
A 5-month-old male child presented with a history of obvious left scrotal swelling for 1 month, which progressively worsened 10 h before the hospital visit. The ultrasound examination exhibited a solid mass in the left scrotum, with echo quite similar to that in the testicle and went up into the abdominal cavity through an identical echogenic band structure. After surgical resection, the pathological examination confirmed that the submitted tissue was spleen tissue with extensive bleeding.
Ultrasound can provide important information regarding the diagnosis of SGF. The possibility of SGF should be considered for further differential diagnosis in the case of similar patients.
脾性腺融合（SGF）是一种罕见的先天性畸形，发生在胚胎发育过程中。SGF 通常表现为左侧阴囊肿胀、左侧腹股沟疝、阴囊肿块或隐睾症。因此，很容易误诊，导致不必要的睾丸切除术。本研究旨在报告一例罕见的 SGF 病例。
一名 5 个月大的男性患儿，因左侧阴囊明显肿胀 1 个月，在就诊前 10 小时逐渐加重而就诊。超声检查显示左侧阴囊内有实性肿块，回声与睾丸相似，并通过相同的强回声带结构向上进入腹腔。手术后病理检查证实送检组织为脾脏组织，广泛出血。
超声检查可为 SGF 的诊断提供重要信息。对于类似的患者，应考虑 SGF 的可能性，以进一步进行鉴别诊断。
